Abstract
The utility model discloses a pair of rivet slip-joint pliers comprising an upper plier body and a lower plier body hinged together in a crossed mode. The upper plier body comprises an upper plier clip and a lower plier handle, wherein an upper positioning hole is formed between the upper plier clip and the lower plier handle. The lower plier body comprises a lower plier clip and an upper plier handle, wherein a lower positioning hole is formed between the lower plier clip and the upper plier handle. The upper positioning hole and the lower positioning hole are arranged front and back in an overlapped mode and a hinge pin is inserted in the upper positioning hole and the lower positioning hole. Round protrusion bosses are respectively arranged at the front end and the rear end of the hinge pin, wherein the diameter of the round protrusion bosses is respectively larger than the diameter of the upper positioning hole and the diameter of the lower positioning hole. The protrusion bosses are respectively abutted against the front lateral side of the upper plier body and the back lateral side of the lower plier body, so that a rivet structure is formed. The hinge pin and the protrusion bosses are integrally formed, so that the hinge pin and the protrusion bosses can not be loose after long-time usage. The pair of rivet slip-joint pliers is long in service life, simple and rapid in manufacture and installation process, and beautiful in appearance.
Description
Technical field
The utility model relates to a kind of instrument, is specifically related to a kind of rivet slip-joint pliers.
Background technology

Technical problem to be solved in the utility model is that to solve rivet slip-joint pliers hinged places easily loosening, the problem that service life is short.
in order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is to provide a kind of rivet slip-joint pliers, comprise together upper of cross-articulation, lower clamp, described upper clamp comprise upper grip head and lower plier handle and both between have locating hole, described lower clamp comprises between lower pliers head and upper plier handle are both and has lower locating hole, on described, lower locating hole forward laps and arranges and be inserted with a bearing pin, the front and back end of described bearing pin is respectively equipped with circular boss, the diameter of described boss is greater than on described, the diameter of lower locating hole, described boss be resisted against described on, form rivet arrangement on the front and back sides of lower clamp.
In above-mentioned rivet slip-joint pliers, also have adjustment hole on described upper clamp or lower clamp, be connected by chute between described adjustment hole and described upper locating hole or lower locating hole.
In above-mentioned rivet slip-joint pliers, described upper and lower binding clip has arc groove on relative side, is evenly equipped with a plurality of anti-slop serrations on the side of described arc groove.
In above-mentioned rivet slip-joint pliers, described anti-slop serrations is zigzag.
In above-mentioned rivet slip-joint pliers, on described upper and lower clamp handle, cover has protective sleeve.
The bearing pin front and back end of the rivet slip-joint pliers that the utility model provides is respectively equipped with circular boss and forms rivet arrangement, and bearing pin and boss are one-body molded, and long-time the use can not become flexible yet, and long service life is made and the mounting process simple and fast good looking appearance.
Description of drawings
The rivet slip-joint pliers that Fig. 1 provides for the utility model face structural representation;
The left TV structure schematic diagram of the rivet slip-joint pliers that Fig. 2 provides for the utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is made detailed explanation.
as Fig. 1, shown in Figure 2, the rivet slip-joint pliers that the utility model provides, comprise together upper of cross-articulation, lower clamp 1, 2, upper clamp 1 comprises upper grip head 11 and lower plier handle 12, have the locating hole (not shown) between upper grip head 11 and lower plier handle 12, lower clamp 2 comprises lower pliers head 21 and upper plier handle 22, have lower locating hole (not shown) between lower pliers head 21 and upper plier handle 22, on, lower locating hole forward laps and arranges and be inserted with a bearing pin 3, the front and back end of bearing pin 3 is respectively equipped with circular boss 31, the diameter of boss 31 is greater than upper, the diameter of lower locating hole, boss 31 be resisted against described on, form rivet arrangement on the front and back sides of lower clamp.The boss 31 of bearing pin 3 and one end is by cutting or cast molding, and after bearing pin 3 was inserted upper and lower locating hole, the other end of bearing pin 3 formed another boss 31 by the cold headers cold-heading.
Have adjustment hole 4 on upper clamp 1 or lower clamp 2, have adjustment hole 4 on lower clamp 2 in the present embodiment, be connected by the chute (not shown) between adjustment hole 4 and lower locating hole.Bearing pin 3 can enter adjustment hole 4 from lower locating hole by chute, thereby changes upper and lower caliper 1,2 width of jaw, but increases the scope of clamping part.
Have arc groove 5 on upper and lower binding clip 11,21 relative sides, be evenly equipped with a plurality of anti-slop serrations 51 on the side of arc groove 5, anti-slop serrations 51 is zigzag.During the clamping circular pieces, the anti-slop serrations 51 in arc groove 5 plays the prevention relative sliding, makes the more firm effect of clamping.
On upper and lower clamp handle 22,12, cover has protective sleeve 6, protective sleeve 6 to play the upper and lower clamp handle 22 of protection, 12 and anti-skidding effect when holding.
Bearing pin 3 front and back ends of the rivet slip-joint pliers that the utility model provides are respectively equipped with circular boss 31 and form rivet arrangements, and bearing pin 3 and boss 31 are one-body molded, and long-time the use can not become flexible yet, and long service life is made and the mounting process simple and fast good looking appearance.
The utility model is not limited to above-mentioned preferred forms, and anyone should learn the structural change of making under enlightenment of the present utility model, every with the utlity model has identical or close technical scheme, within all falling into protection domain of the present utility model.
